Answer:
•Helps to maintain va proper pH in the body which supports cell function.
•Carries electrolytes such as sodium and potassium to our muscles.
Well, first, let's recognize that there is no such thing as a force that is
balanced or unbalanced.
When we say that a group of two or more forces is balanced, we mean
that when you add up all the magnitudes and directions of the forces, the
whole group adds up to zero, so they have the same net effect as if there
were no force at all.
Explanation:
due to its shape st the bottom
Answer:
Density = 3 kg/m³
Explanation:
Given the following data;
Volume = 3m³
Mass = 9 kg
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the formula;
Substituting into the formula, we have;
Density = 3 kg/m³
Answer:
A. Sound comes from the ball every time it bounces.
B. The ball is warmer after it stops bouncing than it was before it
started bouncing
Explanation:
It is evidently shown that the ball shown energy transformation because it produces sound at each bounce and also becomes warmer after the bounce.
The law of conservation of energy suggests that energy is neither created nor destroyed but transformed from one form to another.
- a bouncing ball produces sound energy at each bounce. This is conversion of potential energy initially of the ball into kinetic energy of sound.
- Also, the motion of the ball produces kinetic energy which causes the ball to warm up, this is thermal energy.
- We see that a ball originally with potential energy has yielded the kinetic forms of energy which are sound and thermal energy.
